Attorney To all it may concern:

' rnnmwn'rna rumrmn.

Be .it known that .-I, FRANK E. KEYES, of New York in the county "of NewYork and bi'ew York, have invented certain new and useful Improvements,in Feed- Water Purifiers; and I do hereby declare the following to be afull, clear, and exact description of the invent1on, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to an improvement in feed water purifiers andisdesigned more particularly asan improvement on the purifier patented tome July 24th, 1906, No. 826,580. r In my patent the provided with 'a baextending from the top, some distance from the bottom thereof, and inletand outlet openings near the top and on opposite sides of said baflieplate.

Owing to the increasing use of condensaurifying chamber is e plate orpartition tion from exhaust steam, and drips and re-.

turns from various sources, it is now necessary, in order to properlyprepare the water for use in a boiler, to remove not only scale orincrustation forming substances from the water, but also floatingsubstances, such as oil and vegetable matter, as well as acids oralkalies held in solution.

The object therefore of the present invention is to provide a purifierthat will separate the heavier substances from the water, and alsoseparate or catch all floating matter and all substances lighter thanwater. With these ends in view my invention consists in the parts andcombination of parts as will be more fully explained and pointed out inthe claims.

In the accompanying drawings,

Figure 1 i is a view in longitudinal section of my imis a view insection of right angles to Fig. 1. Fig. 3 is a view in plan 'o thelower-section of the, chamber. Fig. 4 is. a view in elevation of theinclined screen "and its frame, andFig. 5 is a view in plan of the upperscreen. I

The water 'purifieris composed of two seeis provided with a water inlet3 and an outletzl, and a baffle plate or partition 5 located between theinlet and outlet so that all purifier, must be deflected and passdownwardly and terminating of the galvanic pilewi and then up- I Ispecification of Letters Patent.

wardly before reaching the outlet. The baffle plate 5 exten'dsto theopen endof section 1 and alines with the upper end of the battle 6,formed integral with the lower section' 2 of the purifier. This section2 is rounded and larger at its bottom than its top to form a sedimentchamber into which the heavier substancesare precipitated, and isprovided at its top with a flange 7 adapted to make a close fit with theflange 8 onsection'l, the two flan esbeing secured togetherby bolts,thus orminga continuous *hamber through which the water passes from thefeed water heater to and forms in L the boiler. The {baffle plate 6is-integral with the lower section2 of the purifier,

effect a seat or support for the screen 9 which forms a continuation ofthe baflie an which consists of a rectangular frame, and a wire clothsecured at 1ts edges to the frame. The bafiie plate .6, is as shown inFig. 2, cut away, or open at its center, is provided at its lower end onopposite sides of the central opening with the hook shaped seats 10,adapted to receive the lower end of the screen 9, the upper end of thescreen being secured in placeto-the battle plate 6 by q the bolts 11 andthumb nuts 12. The baffle plate 6, and its attached screen rest in aninclined position, soas to gradually enlarge the space between it andthe wal of the purifier on the inlet side" of the battle as clearlyshown in Fig. 1. Secured to the baflieiplate 6 the top of the screen 9,is a galvanic battery or pile com osed of a copper bar l3, zinc plate14;, an a tin plate 15, the bar and two lates being in contact as shownand secured by bolts 11 to the bafiie plate 6. The zinc and adjacent toand tin plates pro e ct downwardly over the upper end of the screen, andif the water passing through the purifier conta ns any acids, thecurrent set up between the plates 1 cause a deposit on the plates. y

The two sections 1 and 2 of the purifier may be separated and insulatedfrom each other by a rubber gasket, and located between the two sectionsonthe outlet side of the baffle plates is the wire screen 17 preferablyreinforced, and held tightly in place by the rubber. gasket 18 shown inFig.1

Communicating with the top of section 1, and in a osition to dischargeonto screen 17 and a so onto the inclined screen 9, is the steam pipe19. By admitting steam to the purifier, all matter adhering to thescreens will be blown off and the interior of the'purifier cleansed, thedeposit in the bot- 5 .tom of the' chamber, and all matter dislodgedfrom the baifles, passing out of the purifier through the washout pipe20 in the bottom. The steam and blow out pipes are provided withsuitable valves as shown.

21 is the oil chamber located above the purifier and communicatingwiththe latter' therein pass downwardly. The oil chamber is provided with asight tube 23, through which the level of the oil may be seen, and alsowith a discharge pipe 24 having a valve 25, through which the 011 isdrawn out of oil chamber 21.

The purifier is designed for connection to the boiler feed pipe betweenthe feed water heater and the boiler, hence the water is always underpressure when the apparatus is in use.

By providing the lower baffle with a screen, and leaving a space betweenthe lower end of the latter and the side wall of the chamber, it will beapparent that if the screen should become clogged, the water will bedeflected past the lower end of the latter I consequently so long as theupper screen 17 is kept open, the water will'have a free passage throughthe purifier, and in its passage will be freed of all substances whichtend to formscale.

" Having fully described my invention what I claim as new and desire tosecure by Letters-Patent, is v 1. Means for precipitating foreign matterin feed water, consisting of a chamber having inlet andoutlet openings,a battle plate or partition separating said openings, and a screenforming ,a continuation of said baflie plate at the lower end of thelatter and terminating above the bottom of said chamber.

2. Means for precipitating foreign matter from feed water consisting ofa chamber having inlet and outlet openings, a battle plate extendingfrom the top of the chantber to apoint below said openings, and a screen'formin a continuation of the baffle plate at the lower end of thelatter, the lower end of the screen being removed from the sidewall ofthe casing whereby the water has'free passage around the screen.

' 3. Means for precipitatingforeign matter in feed water consisting of achamber having inlet and outlet openings near its upper end,- a baffleplate or partition separating sald openings and terminating at. itslower end above the bottom of said chamber, a screen located below andadjacent to the outlet opening and a screen in a plane above the lowerend of the baffle plate or partition and below the first mentionedscreen.

4. Means for precipitating foreign matter in feedwater consisting of achamber having inlet and outlet openings, a baflle plate orpartitionseparating said openings and terminating at its lower end above thebottom of said chamber, a screen forming a continuation of said baffleplate and also terminating at its lower end above the bottom of 'saidchamber and a screen located adjacent to the outlet opening and in a infeed water, consisting of a chamber liaving inlet and outlet openings, abattle plate or partition separating'said openings and provided with aninclined depending screen, I

a screen located below and adjacent to the outlet opening and in a planeabove the lower end of the bafiie plate and said in c'lined screen and asteam pipe having its discharge end. located above both of "said Intestimony whereof, I have signed this specification in the presence oftwo subscribing witnesses. v
